Figures 2 to 4 show one embodiment of the ink cartridge. It is composed of an outer case 20 and an ink bag 21. The ink outlet tube 22 provided in the ink bag 21 is exposed from a central portion of one side surface, and the ink bag 21 is housed in an outer casing 20 in a shape. The outer casing 20 has a two-body structure of a container main body 20a and a lid 20b, and a pressurized air introduction □ 23 for introducing pressurized air is provided in an end area of one side surface exposing one of the ink outlet tubes 22. The ink bag 21 is formed of a liquid-tight film that is deformable under the air pressure of pressurized air, as is known. Contains ink inside. A cylindrical plug body 24 is provided on the front end side of the ink outlet tube 22 so as to contact the outer hole of the ink introduction tube 41 in a liquid-tight manner. Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the pressurized air inlet 23 and the space 25 of the outer casing 20 are connected via a pressure adjusting means 30. Therefore, in order to be suitable for the pressure of the air for discharging the ink from the ink bag 21, an air introduction flow path is formed on the ink bag 21. The pressure adjusting means 30 is an elastic pressure-receiving means (such as a diaphragm) formed of an elastic material such as rubber having air-tightness and elasticity, and an elasticity applying means 32 such as a spring on one side thereof. It is configured to be contained in the atmosphere communication hole forming member 33 with a certain pressure (this example is housed in a case). On the other hand, an atmospheric communication hole 34 is formed at a position in the center region of the elastic pressure receiving plate 31 of the atmospheric communication hole forming member 33. And this paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) ~ -9- 561111 A7 B7 V. Description of the invention (6) (Please read the precautions on the back before filling this page) The side is connected The communication hole 35 is formed in the space 25 of the outer casing. And in this embodiment, a communication hole 36 communicating with the pressurized air introduction port 23 is formed at a position facing the pressurized air introduction port 23 of the atmosphere communication hole forming member 33. The pressurized air introduction port 23 is formed on the exposed end surface of the ink outlet tube 23, and it is in a non-facing position with the pressure adjusting means 30. Of course, the same effect can be achieved. The elastic pressure-receiving plate 31 is formed in a region facing the atmosphere communication hole 34, and has a convex portion 31a so as to securely close the atmosphere communication port 34.

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. On the other hand, the wall surface 40 of the cartridge holder which faces the ink outlet tube 22 of the ink cartridge 9 is arranged to be engageable with the ink outlet tube 22 of the ink cartridge. The ink introduction pipe 41 is formed, and the pressurized air introduction port 23 is formed so as to be engageable with the pressurized air introduction port 23. The ink introduction pipe 41 is connected to the sub tanks 7B, 7C, 7M, and 7Y through a pipe 10. The pressurized air outlet pipe 42 is connected to the exhaust ports of the air pumps 13B, 13C, 13M, and 13Y (Figure 1). In this embodiment, when the ink cartridge 9 is mounted on the holder, first, the ink outlet tube 22 of the ink cartridge 9 is engaged with the ink introduction tube 41 on the recording device side, and then the pressurized air introduction port of the ink cartridge 9 The 23 series is air-tightly engaged with the pressurized air outlet pipe 42 so that the ink cartridge 9 can be installed without leaking ink from the ink cartridge 1. This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) ~ -10- 561111 A7 B7_ V. Description of the invention (7) When the ink cartridge 9 is installed, the detection method is installed by a non-illustrated box When detected, the air pumps 13B, 13C, 13M, and 13Y start and pressurize the air (please read the precautions on the back before filling this page). The pressurized air introduction port 2 3 and the communication hole 3 6 flow into the outer frame. The space 25 of the housing 20. In this embodiment, pressurized air flows into the space of the outer casing 20 because the pressurized air flows through the communication hole 35 of the atmospheric communication hole forming member 33 constituting the pressure adjusting means 30, so it can be used as appropriate. The flow path impedance forming portion of the fluid impedance of the communication hole 35 is set to function, and if an excessive pressure is supplied when the ink cartridge is installed, the elastic receiving plate 31 first receives the excessive pressure and retracts. The atmosphere communication hole 34 is opened, thereby mitigating the rapid pressure change of the outer case 20, preventing the ink bag or the ink supply flow path from being subjected to the rapid pressure change, thereby preventing breakage and the like. It is printed in the current state of the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The pressure of the space of the outer casing 20 is at a slightly atmospheric pressure, and the elastic pressure plate 31 is closed by the plucking force of the plucking means 32. The state of the communication hole 34 is such that all the pressurized air flows into the space 25 of the outer casing 20. As described above, when the pressure of the space 25 of the outer casing 20 rises above the pressure suitable for supplying ink from the ink bag 21 to the auxiliary tank, the elastic pressure bearing plate 31 resists the plucking means 32 and The atmosphere communication hole 34 recedes. As a result, part of the air of the outer casing 20 flows out from the atmosphere communication hole 34, so that the pressure of the outer casing 20 is reduced. The pressure of the space 25 of the outer casing 20 is further reduced to be suitable for the ink bag 2 1 When the pressure for supplying ink to the sub-tank is lower, the elastic pressure bearing plate 31, which is the size of the paper, is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). 561111 A7 B7 V. Description of the invention (8) The atmosphere communication hole 34 is closed by being pushed by the plucking means 32. This process is repeated in accordance with the pressure of the space 25 of the outer casing 20, thereby maintaining the pressure of the outer casing 20 at a pressure suitable for supplying ink. When the ink tank 9 is pulled out from the holder, first, the pressurized air inlet 23 of the ink tank 9 is detached from the pressurized air outlet pipe 42. Therefore, the air in the space of the outer casing 20 is pressurized by the communication hole 36. The air inlet 23 is released from the atmosphere, and the pressure in the space 25 is reduced to atmospheric pressure.

Description of the invention (9) Changes, so that stable ink can be supplied. (Please read the precautions on the back before filling in this page) Furthermore, as shown in Figure 6, when the operating lever 38 is externally operable on the convex part 3 1 a of the elastic pressure plate 31, That is, for example, when the device is stopped under a pressurized state such as an operating power source, the operating lever 38 is still pushed by the driving means 39 to forcibly retract the elastic pressure receiving plate 31 to discharge the pressurized air. Figures 7 and 8 show other embodiments of the ink cartridge of the present invention. It is constituted by having an outer casing 20 that houses the ink bag 21, and in this embodiment, at least a part of the cover 20b has an elastically deformable area 28 that is swellable by pressurized air. . A through-hole 29 for pressurized air outflow is formed in this area 28, and the through-hole 29 is formed so as to protrude into the operating lever 51 of the valve body 50 to be described later. The valve body 50 is printed by the employee's consumer cooperative of the Intellectual Property Office of the Ministry of Economic Affairs, and a convex portion 50a is formed in the area facing the through hole 29 to close the hole. And the plunger means (this embodiment is formed of an elastic material such as rubber, etc.) is used to make the convex portion 50a always abut against the through hole 29 to be deflected, and the surroundings are fixedly formed by an adhesive or a frame 52. At the same time, the above-mentioned action lever 51 is provided on the convex portion 50a. Therefore, in this embodiment, the deformation area of the outer casing 20, the valve body 50, and the operating lever 51 constitute the above-mentioned pressure adjustment means. On the other hand, in the holder constituting the recording device, a gap G1 is formed in a region facing the actuating lever 51 in a state where the ink cartridge 9 is mounted to allow the outer casing to be elastically deformed. A partition wall 43 is formed to receive the displacement of the operating lever 51. In this embodiment, the pressure of the space 25 of the outer casing 20 lies in that the paper size of the specification applies to the Chinese National Standard (CNS) A4 (210X297 mm) -13- 561111 A7 B7 V. Description of the invention (10) At this time, as shown in FIG. 8, the front end 51 a of the operating lever 51 is separated from the melting wall, and the through-hole 29 is sealed (closed) by the valve body 50. (Please read the precautions on the back before filling in this page.) Therefore, the pressurized air from the air pumps 13B, 13C, 13M, and 13Y flows directly into the space 25 of the outer casing 20 through the pressurized air inlet 23. When the pressure of 25 rises, the cover 20b of the outer case 20 corresponds to it. The body 20b expands and deforms outside when receiving air pressure. When the pressure of the space 25 of the outer casing 20 rises above the pressure suitable for supplying ink from the ink bag 21 to the sub-tank, that is, as shown in Fig. 9, the outer casing 20 expands to reduce the gap G2. Therefore, the actuating lever 51 which is displaced (displaced) as the outer casing 20 expands is abutted against the retaining partition wall 43 and is relatively pushed in as the outer casing is displaced. Then, the convex portion 50a of the valve body 50 is separated from the through hole 29, and the space 25 is opened to the atmosphere through the through hole 29, the through hole 50b, and the through hole 52a, and a part of the pressurized air in the space flows out from the through hole 29 The pressure of the outer casing 20 will be reduced. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. With the reduction of the pressure in the space 25, the expansion of the outer shell becomes smaller. The action lever 51 is separated from the partition wall 43 and the valve body 50 will close the through hole 29. Next, the outer casing 20 is displaced to detect the pressure of the space 25. By this displacement, the valve body 50 is separated from the through hole 29, and the pressure of the space 25 of the outer casing 20 is maintained to be suitable for ink supply. The pressure. In this embodiment, the valve body 50 is arranged in an elastically deformable area as an example. However, if a link mechanism such as a lever is connected to the operating lever 51 and the displacement of the operating lever 51 is communicated to him, the valve body 50 can be disposed at another position. This paper size is applicable to Chinese National Standard (CNS) A4 (210X297 mm) -14-561111 A7 B7 V. Description of the invention (11) (Please read the precautions on the back before filling this page) Also, the outer shell As an example, the structure is elastically deformable. The same effect can be achieved by using the structure in which the outer casing 20 opens the window, and the window is closed by an elastic plate.

It can be readjusted by the pressure adjustment means according to the height difference of each ink cartridge or the length of the ink supply tube, so that the deviation or variation of the ink flow rate caused by the pressure of the pump can be reduced. Furthermore, for example, when the ink volumes are different, the volume of the ink bag, the outer casing, and the content space are different from each other, and the optimum air pressure can still be set. Therefore, a variety of ink cartridges may be installed. The predetermined pressure adjustment means can be adjusted by appropriately adjusting the elasticity of the elastic pressure bearing plate 31 or the plucking force of the plucking means 32. In the above-mentioned embodiment, the ink bag is pressurized with a certain pressure with the remaining amount of ink in the ink bag, but it is also possible to use more pressure corresponding to the remaining amount of ink. Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperatives. The pressure adjustment means shown in Fig. 10 shows an embodiment configured to change the above-mentioned pressure ink cartridge as described above. In this embodiment, the detection volume 60 is used to detect the apparent volume of the ink bag, in other words, the remaining amount of ink. The pressing force of the elastic pressure receiving plate 31 is changed in accordance with the displacement. In detail, the first permanent magnet 61 is mounted on the back surface of the elastic pressure receiving plate 31. The second permanent magnet 62 is installed at the front end of the detection plate 60. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) -15-561111 A7 B7 V. Description of the invention (12) (Please read first Note on the back side, please fill in this page again.) According to this embodiment, if the remaining ink quantity decreases and the relative pressure decreases, the detection plate 60 will be displaced, and the second permanent magnet 62 mounted on it is shown in the figure. The reference numeral 62 'is close to the magnet 61 of the elastic pressure-receiving plates 31 and 33. Therefore, the counterforce is enhanced between each other. The permanent magnet 61 moves in the direction of the elastic pressure-receiving plate 31 through the elastic pressure-receiving plate. The pressing force of the spring 32 of the 31 is increased, and the pressure of the space of the outer casing 20 is increased. As a result, ink can be supplied at a constant ink flow rate regardless of the remaining amount of ink. Therefore, on the one hand, it is possible to prevent a reduction in printing quality due to insufficient ink supply, and it is possible to supply ink to the recording head until the ink in the ink bag is used up. Furthermore, regarding the mechanism that changes the pushing force of the diaphragm in accordance with the apparent volume of the ink bag 21, not only the magnetic force, but also the structural system that biases the spring 32 to the side of the diaphragm by a connecting means, can be easily imagined in mechanical design Various ways. Figures 11 (a) and 11 (b). Figures 12 (a) and 12 (b) respectively show one embodiment of the sub-tank as a relay means when the ink of the ink cartridge is supplied to the recording head. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs As shown in Fig. 12, the substrate 70 is formed on its surface with an ink inlet 71 connected to the ink cartridge, and an ink outlet 72 for supplying ink to the recording head. A recess 73 'for forming the ink tank chamber 73 is formed in the central portion. The ink tank chamber 73 is constituted by a film 74 which can be elastically changed by a change in pressure caused by the consumption of ink in the recording head. It is also on the film 74. In order to efficiently transfer the displacement of the film 74 to the later-mentioned action lever, a ring-shaped elastically deformable area is left around, and only a back support by a plate or the like is provided at the central portion. Material 75 to improve rigidity. ^ The paper size applies the Chinese national standard (CNS > A4 specification (210X297 public shame 1 -16-printed by the Employee Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 561111 A7 B7_) 5. Description of the invention (13) And this back support material 75 is based on When injection molding is used to form the film 74, forming this area thicker can make it integral with the film 74. On the surface of the base 70 where the recessed portion 73 'is formed, a groove 76 communicating with the ink outlet 72 is formed. ', And it is closed with a film (in this embodiment, it is closed with a film 74 formed with an ink pool chamber), thereby forming an ink discharge flow path 76. In addition, the ink discharge flow path 74 communicates with the ink pool chamber 73. The port 76a is based on the uppermost position of the ink tank chamber 73 when the sub-tank is provided. Further, it is formed inside the base body 70, and as shown in FIG. The ink of the inflow port 71 is introduced into the groove 77 'of the flow path 77, and is closed with a film 78 to form the ink introduction flow path 77. The symbol 80 is the valve storage chamber described above. The ink tank chamber 73 and the partition wall 81 become The back and abdomen form a recess 80 'in a relational manner, and Here, the plucking means 82 is accommodated (in the present embodiment, the valve body 83 is often pressed against the partition wall 81 to be accommodated by a coil spring). It is provided at the center of the valve body 83 and penetrates the partition wall. 81 is a communication hole 81, and the front end 84a can be contacted with the actuating rod 84 of the film 73. The symbol 85 in the figure indicates a cover for closing. The symbol 86 indicates that it is arranged around the communication hole 81a so that the valve body abuts. In this embodiment, the recording head is closed by a capping means so that the recording head has a suction effect, that is, the ink tank chamber 73 has a negative pressure, and the film 74 is As shown in Fig. 1 (b), it is displaced (shifted) to the valve accommodation chamber 80 side (left side in the figure). As a result, the action lever 84 is resisted by the plucking force of the plucking means 82 and leaves the communication hole 81a.

Description of the invention (14) The flow path system is in a connected state, and the ink in the ink cartridge is passed through: the valve accommodation chamber 80, the communication hole 81a, and the ink tank chamber 73 And into the recording head also. During this process, the air bubbles existing in the flow path also flow into the ink tank chamber 73, move to the top by buoyancy, are sucked out by the recording head through the communication port 76a here, and are discharged to the outside β as described above, When the ink filling of the recording head is completed, the recording head is removed from the recording head. When the capping means is removed, the film 74 is pushed to the outside by the plunger through the action lever 84, and the valve body 83 closes the communication hole 81a. When printing is performed in this state, when the ink is consumed by the recording head, the ink in the ink tank chamber 73 flows into the recording head. In the current state, the communication hole 81a is closed by the valve body 83, so the film 74 is supplied to the ink tank chamber 73 while being displaced to the valve accommodation chamber side. In this way, when the pressure of the ink tank chamber 73 is lower than the pressure set by the plucking mechanism 82, the action lever 84 is resisted by the plucking force of the plucking means and is pushed by the displacement of the film 74, leaving the communication hole 8 1 a. Therefore, as described above, the ink of the ink cartridge flows into the ink tank chamber 73 through the valve accommodation chamber 80, and the pressure of the ink tank chamber 73 increases to move the film 74 to the outside. When the ink tank chamber 73 reaches a predetermined negative pressure as described above, the valve body 83 closes the communication hole 8 1 a and stops the supply of ink to the ink tank chamber 73. When the pressure of the ink tank chamber 73 drops below a predetermined value (regulation) every time the ink is consumed by the recording head, the above process is repeated to supply the ink to the recording head while maintaining a certain negative pressure.
